This volume contains electrographs made by Kinraide from 1897-1900 in his Spring Park Laboratory in Jamaica Plain Massachusetts.  The photos were compiled from glass plate negatives found in hidden rooms beneath Kinraide's home by Jeff Behary in 2006.  Behary replicated spark photos on photographic paper and recreated many of Kinraide's apparatus in addition to restoring an original machine for his family.  Many thanks to Frank Jones and Kelly McJilton for providing the color images of sparks made using Jeff's apparatus.  These images were taken by Kelly in her home near Philadelphia.
